I use a gmail account to test emails, sometimes putting + and extra letters or numbers after the real email address, so I can test forms, flows, etc. without having to create an actual new email address. Today I noticed on my most recent + gmail address, it showed I opened a welcome email, when in fact, I never had opened that email, but only a holiday email – see image below; each time I opened the holiday email it recorded the welcome email being opened, too. On a different + gmail address, it showed I opened the holiday email, when I never opened it for that account. Has anyone else run into this? Any ideas as to why it shows both emails being opened?
